Reclosable packaging system for commercial products has strip or tape with superior film thermosealable to inner face of primary walls, and intermediate layer of pressure-sensitive repositionable adhesive

摘要

A reclosable packaging system comprises a strip (6), band or tape from cut films or sheets having superior film thermosealable to the inner face of the first and second primary walls; and intermediate layer (3) of pressure-sensitive repositionable adhesive. A reclosable packaging system comprises container body having two primary front and rear walls (1, 1') and intermediate walls gussetted between the primary anterior and posterior wall which are sealed on two sides, on the bottom and preferably on the head; and device which allows repeated openings and closures for partial content extractions by a strip, band or tape from cuts films or sheets. The strip comprises a superior film thermosealable to the inner face of a first primary wall. An intermediate layer of pressure-sensitive, repositionable adhesive is applied at full coverage or at longitudinal register in respect to the strip width. An inferior mono-or plurilayer film is thermosealable to the inner face of the second primary wall. The support film or layer is associated to the inner face of the pressure-sensitive adhesive layer. The inner faces of the support film/layer are not thermosealable to the other one by welding of the outer layers to the inner surfaces of the packaging inner walls.
